Tech Note About Knuckle Seal Installation: Ford knuckle seals are the toughest seals to install we have ever come across. The seal is of a complicated unitized design that is easily damaged without the correct installer. In fact, the knuckle seal is virtually impossible to install without damage unless a tool like our one piece, rugged 12 pound QT1515 Knuckle Seal Installer is used to drive or press the seal on. Not only is the seal an extremely tight fit to the shaft, it also must be installed to a specific depth on both the axle shaft and in the knuckle. A damaged seal will allow water to enter and vacuum to escape.
